2 lbs. 11.5 oz. (size XS/S)

Excellent comfort and ventilation for much less weight and bulk than a standard backpacking pack.

Overkill for dedicated ultralight enthusiasts.

A backpacking specialist by nature, Osprey is known for their well-equipped and comfortable designs that can be used for anything from daytime hiking to long-distance hiking trips. The majority of their heavy-duty haulers weigh more than 4 pounds, with sturdy suspension systems as well as a variety of storage options. However, the Eja (and the men’s Exos) is a favorite among those who want to be light and fast with a simple design and a lighter weight. We’ve tested a number of these bags throughout time and the latest Eja looks like an excellent combination of ventilation, comfort and features all in an ultralight design. We’ve compiled our thoughts about the Eja’s overall performance. To find out how it stacks with other backpacks, read our reviews on the top backpacking backpacks along with the most Ultralight backpacks.


Carrying Comfort

Ultralight backpacks cover a range of styles of frameless models with no padding to sturdy haulers that offer the same comfort as conventional models. Its Osprey Eja 58 is a perfect example of the latter, featuring an internal frame that is sturdy and removes sliding, padded mesh on the back and harness and a hip belt that distributes the weight with a minimum of pressure points. Actually, when compared to the majority of ultralight packs I’ve tried, including those from the Granite Gear Crown2, ULA Circuit, and Gregory Facet–the Eja has the highest level for comfort and stability, up to its 30-35-pound weight limit.

The new Eja’s comfort is significantly improved over the previous version. Osprey included a generous amount of padding on the hipbelt and lower back and has eliminated the numerous pressure points that we encountered with the original model. The Eja is now a comfortable fit however, it also comes with significant Lower back support. If you’re in the ultralight pack category it might seem as a lot of cushioning and support (it is actually pressing into the lower part of my back) On the other hand, people who are used to a traditional backpacking bag will be pleased to know that the Eja gives the same kind of experience when it comes to carrying the right way (but at a lower weight). In the end, you’ll be difficult to find a better and more comfortable backpack within this weight class.




Its name is the Osprey Eja just ekes into the ultralight class, with the capacity of two pounds 11.5 ounces for Women’s Size XS/S. To give you an idea, many ultralight models weigh around 2 11.5 lbs (including that of the Hyperlite Mountain Gear 3400 Southwest and the Gossamer Gear Mariposa 60) Frameless models such as that of Mountain Laurel Design Exodus55L could be as light as 1 pound, 2 pounds and 2 ounces. Achieving a weight of more than 2 pounds will give you additional padding, airflow and other features. This is the reason we see packs such as that of the Gregory Facet (2 pounds. 8.8 oz.) as well as the Granite Gear Crown3 (2 2 lbs. 9.3 oz.). 9.3 oz. Eja is the most heavy of the pack (and the most substantial model that made our list of top ultralight backpacks) However, the weight loss is compensated for by the comfort and features for organizing.



Due to its weight and weight, the Eja is likely to be too heavy for many ultralighters Keep in mind that Osprey has an edgier design with their lighter than 2 pounds Lumina and Levity ( check out our detailed overview on this page). However, for those who are transitioning to backpacking and want to move into the world of ultralight backpacking, the Eja has the perfect point of perfect. Osprey’s all-purpose Aura 65 model, as an instance is rated as a mere 4 pounds 7.5 pounds and 7.5 ounces for size XS/S. It offers slightly larger capacity (65 against. the 58L) and comfort for carrying (up up to 40lbs. as compared to. the Eja’s 35lbs.). It’s true that the Aura is definitely luxurious and has several pockets that are extra and provide accessibility to its main compartment. If you’re a fan of every bell and whistle,, it is worth the upgrade to a standard pack however, the Eja is a solid choice with a weight reduction of nearly 2 pounds.




The Eja’s organizational system is an ideal middle between fully loaded packs and ultralight models that are stripped down. There’s one access location to the compartment’s main area (via at the upper) and six pockets that are external which include an lid with two pockets for hipbelts (added to the latest version) and three dump pockets that are external. Osprey added the full-length side compression straps they are perfect for securing large gear such as tents or trekking poles. It was Eja easy to pack. I packed heavy and bulky items such as my sleeping pad and bag as well as my stove and food items inside, and utilized the pockets on the outside to store my on-the-go items (the hipbelt pockets are sized to fit well on my iPhone 11, but it was a squeeze). The floating lid, which isn’t typically found in ultralight bags–provided extra storage space, and Osprey included their FlapJacket case beneath, allowing you to use a lid that isn’t covered, while protecting the main compartment of the pack from humidity.

The organization of the Eja is similar to ultralight backpacks like that of Gregory Facet and Granite Gear Crown3 However, it makes an abrupt turn from the style of a conventional pack, such as the previously mentioned Aura. Its design is very different from the Osprey Aura AG 65 adds a second entrance to its main compartment (via the side zipper) as well as the sleeping bag compartment and two pockets with zippers on the front as well as expanding the capacity that the pockets on hip belts as well as the lid. I’m a big less is more preference, and I much prefer the minimalist design of the Eja. Items are more likely to be lost in the Aura’s ocean of pockets and zippers and I’ve found it more straightforward to create a well-packed backpack with less noises or bells. However, the Eja can be a bit too prominent in my opinion The side and the bottom compression straps are unnecessary complicated, leading to the formation of a bunch and a lengthy adjustment. The Eja definitely is a good choice and is a solid middle ground between Osprey however I would prefer a more sleek design such as that of the Facet as well as the Crown3.




If there’s an area in which it is where the Eja 58 especially excels over other ultralight models, it’s its ventilation. With its AirSpeed suspension backpanels, the backpack features an air channel that allows air to be able to flow between the pack as well as the body. This is a standard design found in backpacking packs however, it is one of the first items to be eliminated when weight savings are the primary goal (as for The Hyperlite 3400 Southwest that has solid Dyneema in rear). The suspended backpanel can add a few extra pounds to the construction, but the improvement in airflow will be worthwhile for numerous users (including the ones who sweat frequently or regularly hike in hot temperatures). It’s important to note that the Gregory Facet 55 also features a similar style, with a smaller weight (and with more padding).



Weather Protection

Its Osprey Eja is built to keep water from getting into the pack and has a waterproof finish on all of the fabrics, including the base, body, and accent. The result is that water will accumulate and then fall off instead of soaking through. Most ultralight packs feature the roll-top feature to prevent rain from getting in the compartment however the Eja does not have a drawstring, instead covering its closure using the lid (or should you prefer to not have a lid you can use flapjacket). Also, my pack was not equipped with a rain cover however, Osprey provides its UltraLight-Pack with a raincover (2.8 pounds.) with an additional $34 price for the medium size (alternatively you could line your bag with a sturdy trash compactor bag, or opt for waterproof stuff bags to protect your equipment in a separate way). The Eja’s water-resistance is on the same level as most ultralight or traditional packs, however it’s important to note that you can upgrade to the Dyneema model (like Hyperlite Southwest) Hyperlite Southwest) to get full protection from water without the weight and the bulk of a raincover.

Quality of Build and Durability

Density of material is typically measured by denier which is most often associated with weight and durability. The greater the denier the heavier, thicker and longer-lasting the fabric. In keeping with its ultralight design The Eja has a thin material 100-denier high-density nylon for the base and body of the pack as well as a more substantial 400-denier accent fabric (the new Eja also has more sturdy stretch mesh pockets which were the weakest point in the earlier model). In contrast, the Osprey all-around Aura is constructed with 210-denier nylon for the body, and 500-denier nylon for the base. The super-stiff Ariel is made of the 420-denier nylon all over. Take a look at the numbers, and it’s evident that you’ll give some toughness in exchange for Eja’s ultralight appearance.

However, among ultralight packs within their price, Eja’s material is par for the norm. For instance, the REI Co-op Flash 55 ($199) makes use of 100and 420-denier nylon and it’s Gregory Facet ($240) utilizes 100-denier nylon for the body, and 210-denier in the base. We’ve tested all three packs for a long time and found that they are able to stand up and are able to withstand the demands of hiking despite their thin materials. If you’re looking to higher in your spending, Dyneema is known for its outstanding strength-to-weight ratio. It’s also utilized in ultralight packs of the highest quality (such as the previously mentioned Hyperlite Southwest). If you’re a committed weekend warrior or intend to take on a long-term trek, a robust case is possible for the Dyneema pack. However, for backpackers who are casual or those who go only a handful of times throughout the year The Osprey Eja should get the job accomplished.




Like many outdoor businesses from 2022 onwards, Osprey began to put more emphasis on environmentally friendly materials and designs. The Eja is a particular model that has an extremely water-resistant finish that is made without harmful chemicals (otherwise called PFC/PFAS-free DWR) as well as the fabric is 100% recycled and bluesign certified. We believe that the best thing you could do for the environment is to restrict the amount of plastic you use (do you really require additional bags?) or get a second hand. If you do decide to purchase something or purchase used, we recommend buying from businesses that make efforts to create a healthier environment.

Sizing and Fit

Women’s Osprey Eja 58 is available with two different sizes: small/extra small and large/medium. The latest version also has an adjustable torso that effortlessly can raise and lower the straps for the shoulder to five different levels (Osprey states that it can adjust to 4 inches. adjustable). I chose an XS/S and instantly set the length of the torso to the height I wanted (I’m barely five feet six inches”). The Eja provided a fantastic all-around fit, which required only a little adjustments after I set it up.

It is important to remember that there are two sizes available for the Eja can be used by women with 13-to 19-inch lengths of torso, but you’ll be able to get more adjustment by using Osprey designs such as those of the Ariel Pro (up to 21 inches. on the back). However, Osprey does not specify the sizes of hips, however with the large straps, the Eja’s hipbelt is likely to fit most body types (those who have particularly slim frames might be unable to use it however). The Eja is able to do the job for mostpeople, but those who are picky about their fit may prefer the cottage-brand model. A majority of these smaller businesses offer customized packs that place a the emphasis on a an appropriate fit. ULA Circuit, for instance. ULA Circuit, for example is available with the choice of four different lengths of torso (ranging between 15 and 24 inches. ) as well as six sizes of hipbelts and the option of J and S-shaped straps for your shoulder.




men’s exos, 58

In the purpose of this test, we tried our female version of the Eja 58, however, Osprey also offers the same design for males as well in the Exos (which is also available in 48, 38, and 58L variants). This Osprey Exos 58 weighs 2 pounds 13.4 pounds for the medium/small size and is available in two distinct colors, it was updated to the spring of 2022 (including the inclusion of hipbelt pockets, stronger stretch-mesh pockets as well as a torso-length adjuster). As with similar to the Eja 58, the Exos 58 comes with a 35-pound weight limit and the price is the same at $240.



What We Like About

  • A great comfort and airflow in the weight of the bike, which includes the backpanel that is suspended and has a breathable but well-padded mesh.
  • The majority of the power and load-carrying capabilities of the traditional design is now is now available in a less bulky and streamlined design.
  • Torso length adjustment is simple to operate and produces an extremely well-fitting pack.
  • It hits a place in terms of organization with hipbelt pockets, practical stretch mesh pockets, and a lid that can be removed to make it float.

“What We Never Do”

  • It’s not enough for the majority of ultralights Heavy and sexy as well as bulky cushioning on your lower back.
  • The compression straps on the sides and bottom straps are built too high, which is making it difficult to adjust them and can cause an uncontrollable bunching.
  • Despite this modification, Eja can accommodate a narrower size range than other packs (including traditional and ultralight models).
  • The nylon is thin and 100-denier inside the body and the base.

The Contest

The two most popular backpacking bag experts, Gregory and Osprey often meet in the middle in their products. For instance, the Facet 55 from Gregory Facet 55 is the closest rival with that of the Osprey Eja 58, featuring an identical design (including the suspended mesh backpanel) and a load limit (35 pounds. ) and an identical price. However, after having logged a lot of miles on both packs there are some differences worth mentioning. The Gregory is generally a less complicated pack that doesn’t include adjustable torso (it’s available in three sizes instead of two, with a 14-20 inch. torso range) and less padding on low back and simple compression straps on the sides and on the bottom. It’s also about 2 pounds lighter. We believe that Facet is our choice. Facet is the more effective of the two designs and slightly more faithful to its ultralight goals. However the Eja retains the luxurious feeling of a traditional backpacking backpack and appeals to more traditional backpackers wanting to change things up by using a the more compact hauler.

If you’re thinking of the Eja it’s likely it’s the case that the Osprey Lumina 60 (and the men’s Levity 60) is being considered. With only 1 pounds 12.8 pounds for women’s smaller size package, the Lumina is the company’s most basic ultralight backpack. But the flaws are evident: First the body of the Lumina is constructed of nylon with a density of 30D, which is so thin , it’s transparent (the most abrasion-prone lower part has 210D). Furthermore, its slimly padded hipbelt soon becomes not able to support the load (Osprey recommends 10-25 pounds.). Also, the model doesn’t have pockets for the hip belt which we believe essential however it is priced higher at $270. This Lumina is worth a look in the event that you think the Eja isn’t enough to your requirements, however, we’d recommend looking at top-quality designs from ultralight experts such as Hyperlite Mountain Gear ULA as well as Gossamer Gear.

The other side of the spectrum is the all-rounder from Osprey that is Aura AG 65. Aura AG 65 ($300). The Aura is fully-featured and extremely comfortable, with various pockets (including two zip pockets on the front and sleeping bag compartment as well as a sides to access the compartment) and the Osprey’s top AntiGravity back panel. The Aura is also more robust with 210-denier nylon across the body, and 500-denier on the bottom. Naturally, each these options add significant amount of weight: Size XS/S Aura AG 65 checks at 4 pounds 7.5 inches and is noticeable larger. The Aura is our choice for trips that require a lot of gear or lengthy trips (it can also carry slightly more than the 40-lb. capacity limit). However, for smaller trips or for those who prefer lighter packs Eja is a great choice. Eja provides the same comfort and ease in an incredibly light design.

Osprey as well as Gregory aren’t the only backpacking pack players. In reality, the vast majority of the top ultralight models are manufactured by smaller, less specific brands like Hyperlite Mountain Gear, ULA, Gossamer Gear, and Granite Gear. Hyperlite Southwest is one of our top picks. Hyperlite Southwest is among our most popular overall packs, with sturdy yet lightweight Dyneema fabrics and a practical roll-top closure (read that there is without lid). This 3400 Southwest (55L) weighs at just one pounds 15.7 pounds and is able to carry up to 40 pounds – blow for blow, which is significantly better as compared to the Osprey. However, there’s several tradeoffs the softly padded Dyneema Backpanel appears less soft and it can get very hot during hot weather. There is no adjustment to the length of the torso (you can choose between five sizes) The Hyperlite costs $355 for the Hyperlite. It’s not hard to match the strength and waterproofing of Dyneema which makes the Southwest an ideal option for those who plan on hiking over a long period of go or want your backpack to last through seasons of rigorous use. For those who are used to backpacks that are traditional will appreciate the Eja’s comfort ventilation, airflow, and more efficient organizational features.

One final option could be Granite Gear’s Crown3 that was updated recently in early 2022 in the Spring of. The cost is just $220 The Crown3 provides the same amount of comfort, and comes it in a light, 2 pound 9.3-ounce package. When compared to Eja It’s also customizable. The lid can be used as a fanny pack once connected to the hip belt, or you can take off the frame sheet, and cut the weight to 2 pounds. However, while Granite Gear’s foam-molded back panel is well-padded however, it’s not quite as comfortable as that of the Osprey for its ventilation as well as the same level of lower back support. Also, you sacrifice some flexibility–the Crown3 for women Crown3 comes in only two sizes that aren’t adjustable for torsos ranging from between 15 and 21 inches (the gender-neutral version comes as three sizes)–but we’ve been extremely pleased with Granite Gear’s fit and ease of use. Overall, if you’re trying to save a little bit of money and don’t have to be concerned about ventilation The Crown3 is worth taking a second look.
